Up to 1,400 job losses are planned at Transport for London (TfL) including in engineering and on the London Underground, according to the Rail, Maritime and Transport (RMT) union.

The RMT said the jobs are at threat due to spending cuts.

Mick Cash, the RMT’s general secretary, said:

As part of the mayor’s efforts to slash spending by £ 5.5bn by 2021 we are now being told that the company plan to cut up to 1,400 jobs in engineering in TfL and in some areas of London Underground.

RMT demands that no cuts take place, so close to the King’s Cross fire anniversary it would be appalling if there was any hacking back on safety.

The mayor needs to stand up for TfL and demand restoration of the full capital grant and proper central government funding for the Tube.”

TfL has been approached for comment.

Last December, TfL unveiled a five-year business plan, involving trimming jobs to save £800m a year. London mayor Sadiq Khan said "a flabby TfL" needed to shape up, through cutting management layers and curbing spending on consultancy and non-permanent labour.

It comes as 2017/18 is the last year the transport body will receive a general grant from the Department for Transport, which helps cover its operating costs.
